Description

Technical Field

[0001] This utility model relates to a frame shockproof structure, and in particular to a frame shockproof structure for a large-area laser cutting machine, belonging to the technical field of large-area laser cutting machines. Background Technology

[0002] In the prior art, such as the utility model with application number 202220840881.8, a multi-dimensional control type large-area laser cutting machine is disclosed. The advantages and positive effects of this utility model are that it can cool down the laser cutting machine as a whole, so as to facilitate long-term operation and improve service life.

[0003] The above-mentioned applications still have shortcomings:

[0004] This type of multi-dimensional controllable large-area laser cutting machine does not have a shock-proof structure between the enclosure and the cutting machine. The vibration generated during the operation of the laser cutting machine will be directly transmitted from the cutting machine to the enclosure shell, which can easily cause a decrease in cutting accuracy, accelerate the wear of equipment parts, and shorten the service life. At the same time, the resonance caused by the vibration will also generate noise, affect the operating environment, and even cause the enclosure shell to loosen, posing a safety risk.

[0005] To address this issue, a shock-resistant frame structure for a fully enclosed laser cutting machine was designed to optimize the aforementioned problems. Summary of the Invention

[0006] The main purpose of this utility model is to provide a shockproof structure for the frame of a laser cutting machine with a large surround, so as to solve the problems mentioned in the background art.

[0007] The objective of this utility model can be achieved by adopting the following technical solution:

[0008] A shockproof structure for a large-area laser cutting machine frame includes an enclosure shell, inside which the cutting machine body is housed. A sealing structure is provided between the enclosure shell and the cutting machine body. An opening is provided at the bottom of the enclosure shell. Side plates are installed on both sides of the cutting machine body. Fixed rods are evenly arranged on one side of the side plates. Vertical rods are installed at the ends of the fixed rods. Inner rings are slidably fitted at both ends of the vertical rods. Ball bearings are rolled on the inner wall of the inner rings. Vertical tubes are fixedly fitted on the outer side of the inner rings. T-shaped rods are symmetrically arranged on one side of the vertical tubes. Springs are fixed at the ends of the T-shaped rods. Horizontal tubes are slidably fitted on the outer side of the T-shaped rods, and one end of the horizontal tubes is fixedly connected to the inner side wall of the enclosure shell.

[0009] Preferred: The sealing structure includes an L-shaped plate and a fixing plate. The L-shaped plates are symmetrically arranged at the two corners of the bottom of the cutting machine body. One bolt is evenly threaded on one side of the L-shaped plate. A telescopic cover is provided at the bottom of the L-shaped plate. The fixing plate is fixedly installed at the bottom of the telescopic cover. Two bolts are symmetrically threaded on both ends of the fixing plate.

[0010] Preferably, the inner wall of the horizontal tube is provided with a damping rubber layer with a thickness of 2-5mm.

[0011] Preferably, the L-shaped panel has an anti-slip pad inside, and the anti-slip pad has an anti-slip texture.

[0012] Preferably, the interior of the vertical tube is symmetrically equipped with buffer rings, and the outer sides of both ends of the vertical rod are equipped with protective rings that match the buffer rings.

[0013] Preferably, a connection hole is provided at the connection between the fixed rod and the vertical rod, and the fixed rod is fixedly connected to the vertical rod by bolts.

[0014] Preferably, the outer side of the vertical rod is provided with a protective layer, and the protective layer is a lubricating oil coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model utilizes the combined use of a surrounding shell, a cutting machine body, a horizontal tube, a T-shaped rod, a spring, a vertical tube, an inner ring, ball bearings, a side plate, a fixing rod, a vertical rod, and a through-hole. When the laser cutting machine vibrates during operation, whether it is vertical vibration, the vibration is weakened by the sliding limit; or horizontal swaying, the vibration is offset by the linkage of the components and the elasticity. This effectively weakens the vibration force transmitted to the surrounding shell during the operation of the laser cutting machine, ensures the stability of the surrounding shell, and reduces the impact of vibration.

[0017] 2. This utility model uses the L-shaped plate, telescopic cover, fixed plate, bolt one and bolt two in combination. Through step assembly, the L-shaped plate and fixed plate are firmly connected to the cutting machine body and the surrounding shell respectively. The telescopic cover expands and contracts with the vibration of the cutting machine body, effectively achieving a seal between the surrounding shell and the cutting machine body, and improving the equipment's protective performance.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment proposes a shockproof structure for a large-area laser cutting machine frame, including an enclosure shell 1, a cutting machine body 2 disposed inside the enclosure shell 1, a sealing structure 3 disposed between the enclosure shell 1 and the cutting machine body 2, an opening 13 at the bottom of the enclosure shell 1, side plates 10 installed on both sides of the cutting machine body 2, the side plates 10 being fixedly installed on both sides of the cutting machine body 2 by bolts, fixing rods 11 being evenly arranged on one side of the side plates 10, and vertical rods 12 being installed at the ends of the fixing rods 11, the middle positions of the fixing rods 11 and the vertical rods 12 being connected by M6 8.8 grade high-strength bolts, and at least 3 bolts being used at each connection position of the fixing rods 11 and the vertical rods 12;

[0031] Both ends of the vertical rod 12 are slidably fitted with inner rings 8. The inner wall of the inner ring 8 is rolled with balls 9. Multiple arc-shaped raceways are evenly opened along the circumferential direction on the inner wall of the inner ring 8. The curvature of the raceways is adapted to the outer contour of the balls 9. The balls 9 are embedded in the corresponding raceways and can roll freely in the raceways. The outer side of the inner ring 8 is fixedly fitted with a vertical tube 7. T-shaped rods 5 are symmetrically arranged on one side of the vertical tube 7. Springs 6 are fixed at the ends of the T-shaped rods 5. The outer side of the T-shaped rods 5 is slidably fitted with horizontal tubes 4, and one end of the horizontal tubes 4 is fixedly connected to the inner side wall of the enclosure shell 1.

[0032] The mechanical vibration energy generated during the operation of the cutting machine body 2 is transmitted to the vertical rod 12 through the side plate 10 and the fixed rod 11. When the cutting machine body 2 vibrates up and down, under the rolling friction of the ball bearing 9, the ball bearing 9 and the inner ring 8 form a certain constraint on the vertical rod 12, so that the vertical rod 12 slides up and down along the inside of the vertical tube 7, weakening the vibration transmitted when the cutting machine body 2 shakes up and down, promoting the dissipation of vibration energy and frequency attenuation, and reducing the vertical impact mechanical energy transmitted from the cutting machine body 2 to the enclosure shell 1. When the cutting machine body 2 shakes horizontally, the left and right shaking cutting machine body 2 drives the side plate 10, the vertical rod 12 and the vertical tube 7 to shake left and right, while the vertical tube 7 pushes the T-shaped rod 5 to slide along the inside of the horizontal tube 4. Under the elastic force of the spring 6, the vibration transmission to the enclosure shell 1 is weakened, and the overall structure's shockproof performance is improved. The connection between the two can keep the cutting machine body 2 in a fixed position and posture during operation, preventing it from being displaced or shaking due to its own vibration or other external forces. Example 2

[0033] The solution in Example 1 will be further described below with reference to its specific working method.

[0034] like Figure 1 and Figure 4As shown, in a preferred embodiment, based on the above method, the sealing structure 3 further includes an L-shaped plate 301 and a fixing plate 302. The L-shaped plate 301 is symmetrically arranged at the two corners of the bottom of the cutting machine body 2. One side of the L-shaped plate 301 is uniformly threaded with bolts 304. The bottom of the L-shaped plate 301 is provided with a telescopic cover 303. The bottom of the telescopic cover 303 is fixedly installed with the fixing plate 302. The fixing plate 302 is made of silicone rubber and maintains good elasticity in the temperature range of -20℃ to 150℃ to ensure the sealing reliability under long-term vibration. The two ends of the fixing plate 302 are symmetrically threaded with bolts 305.

[0035] When the main body 2 of the cutting machine vibrates up, down, left, and right, it causes the L-shaped plate 301 to shake simultaneously. The L-shaped plate 301 pushes and pulls the telescopic cover 303, causing the telescopic cover 303 to stretch and contract and deform, thus playing a sealing role between the shell 1 and the main body 2 of the cutting machine.

[0036] like Figure 2 As shown, in a preferred embodiment, based on the above method, the inner wall of the horizontal tube 4 is further provided with a damping rubber layer with a thickness of 2-5mm. The damping rubber layer absorbs vibration energy and dissipates the mechanical energy generated by vibration through its own elastic deformation, thereby reducing the transmission of vibration between the horizontal tube 4 and other components. At the same time, it can also play a certain role in sound insulation, reducing the noise generated during equipment operation.

[0037] like Figure 4 As shown, in a preferred embodiment, based on the above method, the L-shaped plate 301 is further provided with an anti-slip pad inside, and the anti-slip pad is provided with anti-slip texture. The anti-slip pad is made of nitrile rubber, and the depth of the anti-slip texture on the surface is 0.5-1mm. The anti-slip pad and its anti-slip texture can increase the friction between the L-shaped plate 301 and related components, ensure the stability of the connection, and improve the reliability of the shockproof structure.

[0038] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, the vertical tube 7 is further provided with buffer rings symmetrically arranged inside, and protective rings matching the buffer rings are provided on the outer sides of both ends of the vertical rod 12. The buffer rings and protective rings cooperate with each other to provide a buffering effect when the vertical rod 12 vibrates up and down, reduce the impact between the vertical rod 12 and the vertical tube 7, and effectively reduce the damage of vibration to the vertical tube 7 and the vertical rod 12.

[0039] The buffer ring and the protective ring are made of polyurethane elastomer and have a wave-like structure. When the vertical rod 12 vibrates up and down, the buffer ring absorbs the vibration energy through its own elastic deformation, thereby reducing the impact between the vertical rod 12 and the vertical tube 7.

[0040] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, a connecting hole is further provided at the connection between the fixing rod 11 and the vertical rod 12, and the fixing rod 11 is fixedly connected to the vertical rod 12 by bolts. This fixed connection method by bolts and connecting holes is convenient for installation and disassembly, and facilitates maintenance and replacement of the fixing rod 11 and the vertical rod 12. At the same time, the bolt connection can provide reliable connection strength.

[0041] like Figure 1 As shown, in a preferred embodiment, based on the above method, a protective layer is further provided on the outer side of the vertical rod 12, and the protective layer is a lubricating oil coating. The lubricating oil coating uses a synthetic lubricating oil with high temperature resistance and high viscosity index. The protective layer formed by the lubricating oil coating can reduce the friction between the vertical rod 12 and other components, reduce the degree of wear, and improve the smoothness of sliding of the vertical rod 12. Example 3

[0042] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0043] First, install the L-shaped plate 301 on both sides of the bottom of the cutting machine body 2, so that the inside of the L-shaped plate 301 fits against the two corners of the bottom of the cutting machine body 2. Then, use bolts 304 to pass through the screw holes of the L-shaped plate 301 to the pre-drilled mounting holes in the cutting machine body 2, installing the L-shaped plate 301 at the two corners of the bottom of the cutting machine body 2. Next, move the enclosure shell 1 laterally to cover the outside of the cutting machine body 2. The fixing plate 302 moves with the L-shaped plate 301 to the inner bottom wall of the enclosure shell 1. Align the screw holes at both ends of the fixing plate 302 with the pre-drilled mounting holes on the enclosure shell 1, using locating pins for temporary positioning. Check the tightness of the fixing plate 302 and the fit of the sealing surface. After passing the checks, tighten with bolts 305 to connect the fixing plate 302 to the enclosure shell 1. The mechanical vibration energy generated during the operation of the cutting machine body 2 is transmitted to the vertical rod 12 through the side plate 10 and the fixing rod 11. When the cutting machine body 2 vibrates up and down, under the rolling friction of the balls 9, the balls 9... The inner ring 8 forms a certain constraint on the vertical rod 12, causing the vertical rod 12 to slide up and down along the inside of the vertical tube 7, weakening the vibration transmitted when the cutting machine body 2 shakes up and down, promoting the dissipation of vibration energy and frequency attenuation, and reducing the vertical impact mechanical energy transmitted from the cutting machine body 2 to the enclosure shell 1. When the cutting machine body 2 shakes horizontally, the left and right shaking cutting machine body 2 drives the side plate 10, the vertical rod 12 and the vertical tube 7 to shake left and right, while the vertical tube 7 pushes the T-shaped rod 5 to slide along the inside of the horizontal tube 4. Under the elastic force of the spring 6, the vibration transmission to the enclosure shell 1 is weakened, and the overall structure's shockproof performance is improved. The connection between the two can keep the cutting machine body 2 in a fixed position and posture during operation, preventing it from being displaced or shaking due to its own vibration or other external forces. When the cutting machine body 2 shakes up and down and left and right, it drives the L-shaped plate 301 to shake at the same time, pulling the telescopic cover 303 to stretch and contract, playing a sealing role between the enclosure shell 1 and the cutting machine body 2.

[0044] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
